D) $ 25,\pi $

Show Answer

Answer:

Correct Answer: A

Solution:

Given, height of bucket = 25 cm Radii of top (R) = 20 cm and radii of bottom (r)= 10 cm

$ \therefore $ Capacity of bucket $ =\frac{\pi }{3}h,(R^{2}+r^{2}+Rr) $ $ =\frac{\pi }{3}\times 25,(400+100+200)cm^{3} $ $ =\frac{\pi }{3}\times 25\times 700,cm^{3} $ $ =\frac{\pi }{3}\times \frac{175\times 100}{1000}L=\frac{17.5}{3}\pi L $
